msm: camera: smmu: add new flag to indicate Hw, CDM access

When set, buffers will be mapped within 32-bit region
address space and in patching, if Shared or CmdBUffer is
not set for such buffers - patch the value with right shift
by 8. kmd does as below.

Map:
  Shared or CmdBuffer : Mapped within 32bit.
  HwAndCDMOrShared    : Mapped within 32bit
  others(HwAccess)    : Mapped within 40bit
Patching:
  Shared or CmdBuffer : as is
  HwAndCDMOrShared    : iova >> 8
  others (HwAccess)   : iova >> 8

Shared/CmdBuffer takes precedence over HwAndCDMOrShared.
